DescriptionThe HEDS series are high performance, low cost, two and three channel optical incremental encoders.These encoders emphasize high reliability, high resolution, and easy assembly.
Each HEDS series encoder contains a lensedLED source, an integrated circuitwith detectors and outputcircuitry, and a codewheel whichrotates between the emitter anddetector IC. The outputs of the
HEDS series are two square wavesin quadrature. The HEDS-5540and 5640 also have a third channelindex output in addition to thetwo channel quadrature. This
index output is a 90 electricaldegree, high true index pulsewhich is generated once for eachfull rotation of the codewheel.
The HEDS series utilizes metal codewheels, while the HEDM series utilizes a film codewheel allowing for resolutions to 1024 CPR. The HEDM series is nont available with a third channel
index.
These HEDS series encoders may be quicklyand easily mounted to a motor.For larger diameter motors, theHEDM-5600, and HEDS-5600/5640 feature external mountingears.The quadrature signals and theindex pulse are accessed throughfive 0.025 inch square pinslocated on 0.1 inch centers.Standard resolutions between 96and 1024 counts per revolutionare presently available. Consultlocal Agilent sales representativesfor other resolutions.
